Reversible Control of Carbon Nanotube Aggregation for a Glucose Affinity Sensor

There and back: Through the formation of colloidally stable suspensions of dextran-coated single-walled nanotubes (SWNTs), it was possible to fabricate an affinity sensor based on SWNT photoluminescence. Aggregation could be controlled through introduction of a glucose-binding protein and glucose, which results in a reversible glucose sensor.
